Jiilo the heart. In youni: specimens of Funlosa I have seen globules 

 leave the two abdoniinjil currents, some near the spinnerets and 

 the otljers towards the middle ot" the ventral face, pass round the 

 sides of the abdomen and fall directly into the pericardium. Finally, 

 in some young individuals of Pan/osa and HeJiojihntuis globules, 

 instead of ])eiietrating into the lung, skirted its external border, and 

 then, circul.iting beneath the integument, passed directly into the 

 pericardium. 



In conclusion : the vascular system, which is very little ramified 

 in newly hatched spiders, becomes complicated later on ; the venous 

 blood circulates in a very extensive series of lacuntB. The whole of 

 the venous blood of the cephalothorax is arteriali/.ed before reaching 

 tlie heart : a portion of that of the abdomen returns directly to the 

 jiericardium, and from thence to the heart, without ])assing through 

 the lungs. — Comptes Rcndus, t. cxiv. no. IS (May 2, 1892),

A Conffibiition to tJie Knowledge of the Anatomical Structure of the 

 Herual Orr/ans in the Galeodidce. By A. BiRrLA, of the Zooto- 

 mical Institute of the University of St. Petersburg. (Provisional 

 Communication.) 



The chief results of my investigations into the anatomico-histo- 

 logical structure of the genital organs iu the Galeodidae are the 

 following. 



My studies were conducted upon : — 



a. Gahodes araneoides. Pall. {S & $ ) > 

 h. Galeodts ater, Bir. ( $ ). 



The male genital organs are constructed as follows : — 



1. The external genital aperture is represented by a longitudinal 

 slit in the protuberance of the posterior margin of the first abdo- 

 minal segment ; 



2. Aciniform (so-called accessory) glands, with a chitinized 

 intima, open into the uterus masculinus, which is clothed with 

 chitin ; 



3. Each of the seminal ducts (vasa defcrentia) divides in the third 

 abdominal segment into two rami, which, suddenly narrowing, pass 

 into the filiform testes ; 



4. In the walls of each vas deferens, at their opening into the 

 uterus masculinus, lie aciniform accessory glands, with columnar 

 epithelium, but without an intima ; 



5. At the period of the maturity of the sexual products the end 

 of each ramus of the vasa deferentia, which is histologically indis- 

 tinguishable, swells up into a vesicle and functions as a vesicula 

 peminalis ; 



0. The testes consist of four thin and vwry long coiled tubes, which,
